New merchant character and more!

Hello!

This update has 1 npc merchant with the following animations: idle, interaction - entry, interaction - loop and  interaction - rest.

I'm also providing 2 props with the classic top-down perspective. Previously, these props were only in isometric perspective. This one was a request by one of my supporters, @qomix. 

I'll now start to work on the next "Sewers" asset. Feel free to give any feedback in the comments! Btw, I'll create a Discord server very soon so anyone can reach me there any time (until then you can do the same by DM me on Twitter)

Thank you for your support!
